£600 = 100 + 20%
£600 = 120%—-Divide 12 with—- £50 =10% —— multiply 100 with —— £500=100%
So it is £500.
Explanation:
In order to answer this question we need to understand that the final price of the washing machine (£600) is the price of the machine without VAT (100% of x ) plus VAT (20% of x ). Therefore 120% of x = £600. This can also be written as: 1.2x =600. Make x the subject of the equation by dividing both sides by 1.2 which leaves: x =500 therefore the price of the washing machine without VAT is £500.
